a. Coating alternatives interested in data/alternatives
3. Quenching
a. Use of alternate quench point. Ring Line After 1 hour
4. Procedure Usage
a. Trend towards more formalized use of procedures.
b. Electronic Documentation; update to shift notes when deviation is found
Safety
1. Top head exposure
a. Chemical exposure and steam burns
b. Adhere to good drum checklist
i. 215 F
c. What is the value of measuring that outage
2. Wear and tear on operators
a. Fatiguing injuries Knees, Rotator cuffs
b. Elevator reliability (three trips a shift/12 stories/2592 stairs
3. Standard of Safety
a. Theres always the safety framework, such as; OSHA 1910, EPA RP752
b. What it comes down to is its something you can measure. You have a passion for safety and watch each others backs

c. Monitor feed quality
i. Vac EP, recycle, gravity, etc
3. Heater Fouling
a. Velocity Steam = more is better
b. Generally steam preferred over HC
c. Resonance time vs. Heat flux = Flux wins
